Virtual reality application data associated with a virtual reality application executed on a virtual reality device, a first virtual reality object data associated with a first virtual reality object from the virtual reality application, and virtual reality event data associated with one or more events from the virtual reality application may be received. Robotic arms including a robotic hand may grasp a first physical object which corresponds to the first virtual reality object of the virtual reality application.

BACKGROUND

Robots have been built for many purposes, and are often utilized in situations or scenarios as substitutes for humans. For example, robots may be used in environments such as bomb detection and de-activation, manufacturing processes, or other similar environments. Robots are often built to replicate human actions, such as walking, lifting, speech, cognition, etc. For example, a robot may recognize moving objects, postures, gestures, a surrounding environment, sounds or faces, or interact with humans, such as by facing a person when approached.

FIG. 1 is an illustration of an example robotic system for enabling interaction with physical objects as proxy objects representing virtual objects, according to one or more embodiments. The robotic system 100 of FIG. 1 may include a control unit 110, a display 112, one or more sensors 114, a motor control unit 116, a processor 120, logic circuitry, one or more modules 122, a memory 130, one or more movement portions, such as one or more arms 132 or one or more legs 134, a disk 140, a communication interface 150, and a bus 160. The robotic system 100 may communicate with one or more other devices, such as a virtual reality device 200 over a network 170 using computer communication. According to one or more aspects, the robotic system 100 or one or more of the arms 132 may include grippers, actuators, etc. Additionally, other components or control systems may be utilized in place of the processor 120. For example, according to one embodiment, processing may occur away from (e.g., as with ‘beam’ robotics) the robotic system 100 and the robotic system 100 may receive commands via the communication interface 150.

According to one or more aspects, a user may wear or experience virtual reality through the virtual reality device 200. For example, the virtual reality device 200 may be a virtual reality headset and may include a personal computer, processor, memory, etc. The virtual reality device 200 may run or execute a virtual reality application and a display of the virtual reality device 200 may render a virtual reality environment for the user. For example, the virtual reality application may be a racing game where the user experiences race car driving through the virtual reality headset. Thus, in this example, the user is presented (e.g., the display of the virtual reality device 200 renders) with the racing environment, a virtual reality image of the user's body or hands, and a virtual reality steering wheel.

In this regard, the robotic system 100 complements the virtual reality device 200 by grasping a real world or physical object which may resemble, but does not necessarily have to be a steering wheel. For example, the robotic system 100 may grasp or hold a Frisbee, to which the user appears as the steering wheel (e.g., because the user is wearing or experiencing virtual reality through the virtual reality device 200). Further, the user may interact with the Frisbee, using it to drive and control the virtual reality race car. Thus, when the user turns or rotates the Frisbee (e.g., utilizes it as a steering wheel), the robotic system 100 continues to grasp the Frisbee, provides tactile feedback, haptic feedback, or force feedback to the user through the Frisbee, and communicates the user's real world movement of the Frisbee to the virtual reality device 200, which enables the virtual reality device 200 to render movements or the virtual reality race environment through the virtual reality headset. In other words, the robotic system 100 may provide haptic feedback or force feedback by grasping an object associated with the virtual reality application while enabling a user to interact with that object. In this way, the robotic system 100 enables a user to interact with a physical, real world object as if that object were a control mechanism or control device within the virtual reality environment, and to effect changes to the rendering of the virtual reality environment based on the real world interaction with the physical object.

According to one or more aspects, the user may wear or experience virtual reality through the virtual reality device 200 or the virtual reality headset, running or executing the virtual reality application. The display of the virtual reality device 200 may render a virtual reality object for the user. For example, the virtual reality object may be provided to the virtual reality device 200 in the form of a CAD file. In this regard, the robotic system 100 may have different objects (e.g., primitive objects, shapes such as cylinders, cones, cubes, etc. or different textures, smooth, squishy, furry, hard, soft, etc.) available to grasp or touch. When the user reaches out into the virtual reality environment to grasp the virtual reality object, the robotic system 100 may detect or receive the position of the user's hand and ‘match’ what the virtual reality object should feel like by grasping one or more of the physical objects and moving those objects within reach of the user to mimic the feel of the portion of the virtual reality object that the user is touching or in contact with. Further, interactions made with the real world object may be reflected in the virtual reality device 200 or display. For example, if the virtual reality environment includes a wall, the robotic system 100 may grasp or hold a sheet of paper up to the user. If the user's tears a hole in the sheet of paper, the virtual reality device 200 may render the wall with a hole or as crumbling down, for example. In any event, one or more of the components of the robotic system 100 of FIG. 1 will be described in greater detail below.

The communication interface 150 may receive data from the virtual reality device 200, one or more mobile devices, one or more other systems, etc. over the network 170. The communication interface 150 may receive virtual reality application data associated with a virtual reality application executed on the virtual reality device 200. Examples of virtual reality applications include virtual reality racing games, virtual reality training applications, flight simulators, instrument simulators, experience simulators, etc. The virtual reality device 200 may include a virtual reality headset or a virtual reality display.

The communication interface 150 may receive a first virtual reality object data associated with a first virtual reality object from the virtual reality application. In other words, the communication interface 150 may receive virtual reality object data associated with virtual reality objects which are ‘located’ in the virtual reality environment and seen by the user on the virtual reality device 200. For example, if the virtual reality application is a race car simulator, the user may see a virtual reality steering wheel rendered on the display of the virtual reality device 200. In this example, the virtual reality object is the virtual reality steering wheel. The communication interface 150 may receive virtual reality object data from the virtual reality device 200 pertaining to the virtual reality steering wheel (e.g., a size, a shape, a location relative to the user, etc.). In this way, the robotic system 100 may utilize the virtual reality object data to mimic or ‘synchronize’ objects in the real world in relation to the virtual reality objects in the virtual environment.

The communication interface 150 may receive virtual reality event data associated with one or more events from the virtual reality application. Examples of events associated with the virtual reality application include changes in the rendering of the virtual reality device 200 or virtual reality display. This virtual reality event data may be based on events in the real world or events in the virtual reality environment.

For example, if the user (e.g., wearing the virtual reality headset) walks forward in the real world, the user walking is a real world event which, when detected by the virtual reality device 200, causes the virtual reality device 200 to render the user walking forward in the virtual reality environment. The rendering of the user walking in the virtual reality environment may be the virtual reality event data which is based on the real world event of the person physically walking through the real world environment. Stated another way, the virtual reality event data may be indicative of an event from the virtual reality application caused by the user approaching the physical object in the real world corresponding to the virtual reality object.

As another example, if the user is wearing the virtual reality headset, and there is a virtual reality object (e.g., a virtual reality bird) which passes by, the virtual reality device 200 may render the virtual reality bird. The rendering of the virtual reality bird may be the virtual reality event data which is based on the virtual reality environment event of the bird flying by the user.

In any event, the robotic system 100 may receive information or the virtual reality event data associated with these events from the virtual reality application, and grasp physical objects with which the user may interact with accordingly.

The memory 130 may store data received by the communication interface 150 as one or more instructions. For example, the memory 130 may store the virtual reality application data, the first virtual reality object data, and the virtual reality event data. This enables the robotic system 100 to determine what is being rendered to the user in terms of the virtual reality environment, virtual reality objects, the virtual version of the user with respect to the virtual reality objects, and changes which may occur (e.g., as a result of the user walking or movements associated with the virtual reality objects) between the virtual reality environment, the virtual reality objects, or the virtual reality image or version of the user. In any event, the processor 120 or modules 122 of the processor 120 may utilize the virtual reality application data, the first virtual reality object data, or the virtual reality event data to generate or calculate one or more motor control instructions, which may command the robotic system 100 to grasp and move physical objects in accordance with what is being presented or rendered on the virtual reality device 200 (e.g., virtual reality event data). The memory 130 may also store one or more instructions generated by the processor 120 or modules 122 of the processor.

The motor control unit 116 may control one or more movement portions, such as one or more appendages of the robotic system 100. Examples of movement portions include one or more arms 132, one or more legs 134, tracks, wheels, bearings, joints, etc. For example, one or more of the arms 132 of the robotic system 100 may include a robotic hand 332. The robotic hand 332 may grasp a first physical object which corresponds to the first virtual reality object of the virtual reality application. In one or more embodiments, one or more of the sensors 114 may detect when two or more physical objects are available and the processor 120 may select a physical object from the two or more physical objects to grasp based on the virtual reality application data, the virtual reality object data, or the virtual reality event data. For example, if a block of wood and a Frisbee are available or detected by one or more of the sensors 114, the virtual reality application is a race simulator application, and the virtual reality event data indicates that a steering wheel is being rendered to the user, the processor 120 may generate motor control instructions which command the legs 134 of the robotic system 100 to move to a predetermined distance within the Frisbee, and motor control instructions which command the arms 132 of the robotic system 100 to pick the Frisbee up or otherwise grasp the Frisbee based on one or more properties associated with the Frisbee (e.g., the shape) detected by one or more of the sensors 114.

As another example, the motor control module of the processor 120 may generate one or more motor control release instructions for one or more of the robotic arms 132 commanding one or more of the robotic arms 132 to release grasping of a grasped physical object. The processor 120 may execute one or more of the motor control release instructions based on the virtual reality event data, a position or a bearing of a user relative to the first physical object, detecting no user interaction with the first physical object, or upon receiving or generating another set of grasp instructions for another physical object (e.g., taking higher priority), such as a second physical object. In other words the robotic system 100 may release the physical object when virtual reality event data indicates that the user is not within a predetermined distance of a corresponding virtual reality object, the user is not facing the corresponding virtual reality object, the user is no longer interacting with the corresponding virtual reality object, it is inferred by the processor 120 that the user is not interested in the corresponding virtual reality object, etc.

The motor control module of the processor 120 may generate one or more motor control grasp instructions for one or more of the robotic arms 132 to command one or more of the robotic arms 132 to grasp a second physical object based on an inferred user interaction with a corresponding second virtual reality object. For example, if one or more of the sensors 114 detect that the user is approaching the corresponding second virtual reality object, the user is focused on or viewing the corresponding second virtual reality object, etc. In any event, the processor 120 may execute one or more of the motor control grasp instructions based on the virtual reality event data (e.g., the user moving toward the corresponding second virtual reality object) or a position of the user relative to the second physical object or the corresponding second virtual reality object. In this way, the robotic system 100 may be prepared, infer, or anticipate user interaction with one or more virtual reality objects and grasp corresponding physical objects in preparation for user interaction with the same based on virtual reality event data (e.g., the user interacting or beginning to interact with the virtual reality object).

Further, one or more of the sensors 114 may, detect a user interaction with the first physical object. In other words, the sensors 114 may determine whether the user is in contact with the physical object, an amount of force that the user is applying to the physical object, a direction of force applied to the physical object, etc.

The sensors 114 may also detect a position of the user relative to the physical object. For example, if the virtual reality event data indicates that the user is ten meters away from a virtual reality object rendered on the virtual reality device 200, the motor control module of the processor 120 may generate one or more motor control movement instructions for one or more of the movement portions, such as the legs 134 of the robotic system 100, thereby moving the robotic system 100 (which is grasping the physical object) away from the user until the virtual reality event data indicates that the user is reaching for the virtual reality object, at which time the motor control module may generate motor control instructions commanding the robotic system 100 (or arms 132 thereof) to move the physical object into the user's reach.

In one or more embodiments, one or more sensors 114 of the robotic system 100 may detect the position of the user relative to the physical object or the robotic system 100. In other embodiments, the communication interface 150 of the robotic system 100 may receive the position of the user relative to the physical object or the robotic system 100 from the virtual reality device 200 (e.g., which may implement sensors 220 of its own).

Further, one or more of the sensors 114 of the robotic system 100 may detect the position of the physical objects relative to the robotic system 100. This enables the robotic system 100 to move around and pick up or grasp a variety of physical objects based on movement of the user in the real world environment or based on virtual reality event data indicative of virtual reality objects moving towards or away from the user in the virtual reality environment. In one or more embodiments, the sensors 114 of the robotic system 100 may scan or search the real world environment for one or more available objects to grasp or hold. For example, the motor control module of the processor 120 may generate one or more motor control movement instructions for one or more of the movement portions to command one or more of the movement portions to move the robotic system 100 within a predetermined distance of the second physical object (e.g., which the processor 120 may infer that the user is going to interact with). In this regard, the processor 120 may execute one or more of the motor control movement instructions based on the virtual reality event data or a position of the user relative to the second physical object to move the robotic system 100 towards or way from the second physical object based on the virtual reality event data.

In one or more embodiments, the motor control module of the processor 120 may generate one or more motor control movement instructions commanding the robotic system 100 to mitigate robotic system interaction with the user while the user is interacting with the physical object. For example, if the user is touching or feeling his or her way around a physical object, such as a flat sheet representing a wall, the robotic system 100 may adjust the grip or grasp of the flat sheet (e.g., the physical object) based on the movement of the user's hands. In other words, if the user is ‘feeling’ his or her way around the flat sheet and comes within a predetermined distance of the arms 132 of the robotic system 100, the motor control module of the processor 120 may generate one or more motor control movement instructions commanding the arms 132 to shift position, away from the hands of the user (e.g., while maintaining the mimicking or parallelism between the real world environment and the virtual reality environment).

In one or more embodiments, the physical object may be manipulated by the motor control module of the processor 120 of the robotic system 100 to be relocated as the user is interacting with the physical object in a scenario where the user is experiencing or viewing a virtual object associated with a size greater than the physical object. For example, the robotic system 100 may use the physical object of a book to represent a large wall, placing the book in spots or locations where the virtual reality wall appears to the user and when the user reaches for that portion of the virtual reality wall. In this way, the robotic system 100 may relocate the physical object around in the real world space or environment. Other examples, such as the physical object being utilized to represent a virtual reality car are contemplated as well.

As discussed, one of more of the sensors 114 of the robotic system 100 may measure one or more aspects associated with the user interaction with the physical object, such as an amount or magnitude of force associated with the user interaction of the physical object, a direction of the force, a magnitude of the force, a duration of the force, associated acceleration, velocity, jerk, torque, angular velocity, angular acceleration, etc. Keeping in mind that the virtual reality device 200 may render the physical object as a control device within the virtual reality application, the user may interact with the physical device accordingly. Returning to the race car simulator example, the virtual reality steering wheel is rendered by the virtual reality device 200. The virtual reality steering wheel may be an example of a control device within the virtual reality application of the race car simulator. Based on the measurements associated with the user interaction of the Frisbee being grasped by the robotic system 100, a virtual reality event module of the processor 120 may generate a set of virtual reality event data.

In other words, if a first set of virtual reality event data includes the virtual reality version of the user driving down a straight road, and the user turns the Frisbee (e.g., acting as the steering wheel to the vehicle in the virtual reality environment), the virtual reality event module of the processor 120 may generate a second set of virtual reality event data based on the user interaction of manipulating or turning the Frisbee with a measured amount of force. For example, the communication interface 150 may transmit data associated with the amount of force from the user interaction to the virtual reality device 200 as virtual reality event data (e.g., indicative of a steering wheel turn). This generated set of virtual reality event data may be to the virtual reality device 200. In this way, a real world user interaction with a physical object as a proxy object representing a virtual object may occur, and the aspects or characteristics measured and associated with the user interaction may effect or cause changes in the virtual reality environment. The virtual reality device 200 may render one or more virtual reality events based on this input.

As another example, if the sensor 220 of the virtual reality device 200 detects that the user picks up a physical object, such as a ball, the display 210 of the virtual reality device 200 renders a virtual reality object corresponding to the ball in the virtual reality environment at a corresponding position to the physical ball in the real world environment. The physical ball may be rendered as a different virtual reality object, in one or more embodiments, such as a virtual reality trophy, for example. In any event, the virtual reality device 200 may render the virtual reality object based on movement or coordinates of a corresponding physical object in the real world environment.

In response to one or more of the virtual reality events, a force feedback module of the processor 120 may generate one or more force feedback instructions for movement of one or more of the robotic arms 132. Force feedback may include haptic feedback. For example, if the user is trying to turn right, but there is a concrete barrier in the way of the vehicle within the race simulation virtual reality environment, the force feedback instructions generated by the force feedback module may cause resistance to the right turn (e.g., the user interaction with the Frisbee or the physical object) that the user is attempting to make by turning the physical object grasped by the robotic system 100. In any event, other types of force feedback may be provided, such as vibration or rumbling, when the user is driving through a gravel or bumpy road in the race simulation virtual reality environment, for example. Thus, the force feedback instructions may command one or more of the robotic arms 132 to move while maintaining grasp of the physical object. In this way, a user may receive force feedback or tactile feedback from the robotic system 100 when touching, contacting, or interacting the physical object grasped by the robotic system 100. Further, the robotic system 100 enables the user to interact with virtual objects in the virtual reality environment by manipulating the physical object grasped by the robotic system 100.

In one or more embodiments, the force feedback module may generate one or more force feedback instructions to provide an appropriate or corresponding reactive force to a virtual reality event, to constrain movement to rotation on a corresponding axis for a device or virtual reality object within the virtual reality environment, or match one or more forces (e.g., bumps, turns) to from the content of the virtual reality application (e.g., otherwise correspond to the virtual reality event data).

The processor 120 may execute one or more of the force feedback instructions based on detecting the user interaction with the physical object and based on the virtual reality event data. For example, when the user is grasping the physical object (e.g., the Frisbee), the virtual reality event data indicates that the user is driving a vehicle with a concrete barrier on the right in the virtual reality environment, and the user attempts to turn right into the virtual reality concrete barrier, the processor 120 may execute the force feedback instructions to resist, rumble, or vibrate the physical object grasped by the robotic system 100 (e.g., and the user). In this way, the robotic system 100 disclosed herein may provide multi-purpose force feedback by selecting an appropriate physical object to grasp and presenting that physical object in accordance with virtual reality events associated with virtual reality event data.

One or more advantages may thus be provided because existing haptic feedback devices are single purpose devices, such as a game controller, for example. In other words, a game controller is merely setup to be a controller for a game, while the robotic system 100 may perform a variety of functions (e.g., other functions, such as being a multi-functional mobile assistant, walking, running, kicking a ball, serving meals, etc.). Thus, the robotic system 100 enables adaptive force feedback to be implemented based on the virtual reality application or associated virtual reality event or scenario. Other examples of functions may include providing a physical objects as a proxy steering wheel, flight stick or control stick, a leash for walking a virtual pet, a bat for a baseball simulation, a remote, etc.

The control unit 110 may include the processor 120, one or more of the modules 122, the memory 130, the disk 140, and the communication interface 150. The disk 140 may store one or more of the scenarios described herein, thereby enabling the processor 120 to recognize instances where execution of instructions may be proper. The bus 160 may enable computer communication between one or more components of the robotic system 100 or from the robotic system 100 to the virtual reality device 200. The display may render one or more notifications associated with operation of the robotic system 100 (e.g., errors messages, menus, instructions, help, battery level, etc.).

FIG. 2 is an illustration of an example virtual reality device 200 for enabling interaction with physical objects as proxy objects representing virtual objects, according to one or more embodiments. The virtual reality device 200 may include a display 210, sensors 220, a processor 230, a memory 240, a disk 250, a communication interface 260, and a bus 270. The communication interface 260 of the virtual reality device 200 may receive data or information from the robotic system 100 and render virtual reality objects, virtual reality events, etc. accordingly.

FIG. 3 is an illustration of an example robotic system for enabling interaction with physical objects as proxy objects representing virtual objects, according to one or more embodiments. In FIG. 3, the robotic system 100 includes a head 310, a body 320, the arms 132, hands 332, and the legs 134. Other examples of robotic systems are contemplated, such as drone robotic systems with graspers or actuators as arms, scada style arms, miimo style arms, etc.

FIG. 4 is an illustration of an example robotic system for enabling interaction with physical objects as proxy objects representing virtual objects, according to one or more embodiments. FIG. 4 is an example of the robotic system 100 holding an exemplary physical object 410 (e.g., using arms 132 and hands 332). In this example, the physical object 410 is a steering wheel, although other physical objects are contemplated.

FIG. 5A is an illustration of an example robotic system where interaction with physical objects as proxy objects representing virtual objects occurs, according to one or more embodiments. In FIG. 5, a user 510 is wearing the virtual reality device 200 and interacting with the physical object 410, which is held by the arms 132 of the robotic system 100. The user 510 may interact with the physical object 410, such as by applying a force to the physical object 410. In this example, the force is a rotational force 512, and the robotic system 100 is constraining the physical object 410 to movement rotationally on an axis, as a steering wheel would be in a real world vehicle. The robotic system 100 may apply a counter rotational or reactive force 514 based on virtual reality event data, for example. In one or more embodiments, the robotic system 100 may constrain the physical object 410 to movement rotationally on the single axis until a virtual reality event occurs, such as a virtual reality car crash, for example. In such an example, force feedback may be provided along other axes (e.g., if the racecar crashes, the wheel could move suddenly along one of the previously constrained axes, providing an element of surprise or realism). In this way, the robotic system 100 advantageously provides several degrees of freedom of movement which not provided by typical controllers. The robotic system 100 or the virtual reality device 200 may not necessarily operate in a 1:1 correspondence, although this is possible in one or more embodiments. For example, a forty degree turn of the physical object 410 may be rendered as a forty-five degree turn in the virtual reality environment. In other words, compensation or adjustments between the mapping from the physical environment to the virtual reality environment may be made by the robotic system 100 or the virtual reality device 200 or processors thereof.

In one or more embodiments, the user 510 may interact with one or more portions of the robotic system 100 as the physical object. For example, the hands 332 of the robotic system 100 may be commanded to make a fist, which the user 510 could interact with, such as rotating the first as a virtual reality doorknob, for example. In this way, portions of the robotic system 100 may server as the physical object acting as a proxy for a corresponding virtual reality object. As another example, the finger of the hand 332 of the robotic system 100 may be utilized as a virtual reality pen.

FIG. 5B is an illustration of an example virtual reality system corresponding to the scenario associated with the robotic system 100 of FIG. 5A, according to one or more embodiments. As seen in FIG. 5B, the user is experiencing a virtual reality environment seen through the display 210 of the virtual reality device 200. In other words, the virtual reality device 200 is running or executing the virtual reality application of a driving simulation game or a race simulation game here. The virtual reality device 200 may transmit virtual reality application data via the communication interface 260 to the communication interface 150 of the robotic system 100. Additionally, virtual reality object data, such as a first virtual reality object data associated with a first virtual reality object from the virtual reality race simulation game may be transmitted by the communication interface 260 to the communication interface 150. Similarly, virtual reality event data associated with one or more events from the virtual reality application may be transmitted by the communication interface 260 to the communication interface 150 as well.

As previously discussed, the virtual reality application data, the first virtual reality object data, and the virtual reality event data may be stored in the memory 130 or the disk 140 of the robotic system 100 as one or more instructions and utilized to generate one or more instructions to facilitate force feedback as provided through interaction with physical objects as proxy objects representing virtual objects. In this regard, the robotic arms 132 of FIG. 5A (e.g., including robotic hands 332) may grasp a physical object 410. The physical object 410 corresponds to the virtual reality object illustrated in FIG. 5B of the virtual reality or race simulation application.

With reference to FIG. 5A, the robotic system 100 or sensors 114 thereof may detect a user interaction (e.g., the rotational movement or rotational force 512 applied by the user 510) with the first physical object 410, which is the mock steering wheel in FIG. 5A. As virtual reality events occur within the virtual reality application, this virtual reality event data may be transmitted from the virtual reality device 200 to the robotic system 100. When called for by the virtual reality application (e.g., prompted or based on a virtual reality event), the force feedback module of the processor 120 may generate one or more force feedback instructions for one or more of the robotic arms 132. As an example, if the vehicle of the virtual reality race simulation application crashes, the processor 120 may generate force feedback instructions commanding one or more of the robotic arms 132 to vibrate the physical object 410 (while maintaining grasp of the physical object 410). Thus, if the user 510 is in contact, touching, or grasping the physical object 410, tactile feedback or force feedback would be provided from the robotic system 100 (or arms 132 or hands 332) to the physical object 410 to the user 510. The processor 120 may execute one or more of the force feedback instructions based on detecting the user interaction with the first physical object 410 and based on the virtual reality event data (e.g., a crash in the virtual reality environment).

Other examples of virtual reality events or corresponding virtual reality event data which may trigger the generation and execution of force feedback instructions may include a contact between a virtual reality version of the user and one or more virtual reality objects, virtual reality wind, virtual reality environment aspects (e.g., driving on a bumpy road) in the virtual reality environment, etc.

FIG. 6A is an illustration of an example robotic system where interaction with physical objects as proxy objects representing virtual objects occurs, according to one or more embodiments. FIG. 6B is an illustration of an example virtual reality system corresponding to the scenario associated with the robotic system 100 of FIG. 6A, according to one or more embodiments. With reference to FIGS. 6A-6B, the user 510 (e.g., wearing the virtual reality device 200) may see a virtual reality representation of his or her hand 602′ touching a surface 610′ as rendered on the virtual reality display 210 in the virtual reality environment. Concurrently or simultaneously, the robotic system 100 may grasp a physical object 610 which may be shaped similarly to the surface 610′ (or a portion of the surface such as when a smaller physical object is being utilized as a proxy for a larger virtual object—e.g., when a cube or block is used to represent a virtual reality car) and bring the physical object 610 in contact with the user's hand 602 in accordance with the virtual reality representation of the user's hand 602′ touching the virtual reality surface 610′.

In one or more embodiments, different movement speeds, movement actions, or types may be provided by the robotic system 100 based on the perceived virtual reality object or one or more attributes associated therewith. For example, if the virtual reality object is a virtual reality vehicle or car, the robotic system 100 may adjust an interaction of a physical object with the user to closer simulate the desired texture or coefficient of friction of the vehicle (e.g., slide the physical object at a different speed based on the perceived texture of the virtual reality object).

FIG. 7 is an illustration of an example 700 robotic system and virtual reality system for enabling interaction with physical objects as proxy objects representing virtual objects, according to one or more embodiments. In FIG. 7, as the user 510 moves 722 and feels his or her way along a ‘wall’ (e.g., the physical object 710) using his or her hand 602, the robotic system 100 may move 712 in correspondence based on what the user 510 sees in the virtual reality application in the virtual reality device 200.

FIG. 8 is an illustration of an example flow diagram of a method 800 for enabling interaction with physical objects as proxy objects representing virtual objects using a robotic system, according to one or more embodiments. The method 800 may include receiving virtual reality application data associated with a virtual reality application executed on a virtual reality device at 802 (e.g., this enables the robotic system to determine what virtual reality application the user is using), receiving a first virtual reality object data associated with a first virtual reality object from the virtual reality application at 804 (e.g., this enables the robotic system to determine the virtual object with which a user may interact with and grasp a corresponding object), receiving virtual reality event data associated with one or more events from the virtual reality application at 806 (e.g., this enables the robotic system to determine whether the user is interacting with the virtual reality object and how that virtual reality object is reacting back to the user), grasping a first physical object which corresponds to the first virtual reality object of the virtual reality application using one or more robotic arms including a robotic hand at 808 (e.g., when the user interacts with the virtual reality object, the robotic system grasps the physical object for the user to interact with in the real world in a corresponding manner), detecting a user interaction with the first physical object using one or more sensors at 810 (e.g., if the user moves the physical object, the physical object may react (e.g., if the virtual reality object is a fish, the fish may flop) or provide some other input or event in the virtual reality world), generating one or more force feedback instructions for one or more of the robotic arms (e.g., the physical object may be forced to react as the virtual reality object would), wherein the force feedback instructions command one or more of the robotic arms to move while maintaining grasp of the first physical object at 812 (e.g., this reaction may be caused by having the robotic system hold an object and move the object while the user is touching or interacting with the physical object), and executing one or more of the force feedback instructions based on detecting the user interaction with the first physical object and based on the virtual reality event data at 814.

In one or more embodiments, the robotic system 100 may be capable of planning and executing a kinematic path for the robotic system 100 itself or for one or more physicals objects which are released such that the physical object interacts with the user at a predetermined time, position, velocity, energy, etc. in correspondence with one or more virtual reality events from the virtual reality device 200.

One or more embodiments may employ various artificial intelligence (AI) based schemes for carrying out various aspects thereof. One or more aspects may be facilitated via an automatic classifier system or process. A classifier is a function that maps an input attribute vector, x=(x1, x2, x3, x4, xn), to a confidence that the input belongs to a class. In other words, f(x)=confidence (class). Such classification may employ a probabilistic or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to prognose or infer an action that a user desires to be automatically performed.

As used in this application, “or” is intended to mean an inclusive “or” rather than an exclusive “or”. Further, an inclusive “or” may include any combination thereof (e.g., A, B, or any combination thereof). In addition, “a” and “an” as used in this application are generally construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. Additionally, at least one of A and B and/or the like generally means A or B or both A and B. Further, to the extent that “includes”, “having”, “has”, “with”, or variants thereof are used in either the detailed description or the claims, such terms are intended to be inclusive in a manner similar to the term “comprising”.

Further, unless specified otherwise, “first”, “second”, or the like are not intended to imply a temporal aspect, a spatial aspect, an ordering, and so on. Rather, such terms are merely used as identifiers, names, etc. for features, elements, items, and so on. For example, a first channel and a second channel generally correspond to channel A and channel B or two different or two identical channels or the same channel. Additionally, “comprising”, “comprises”, “including”, “includes”, or the like generally means comprising or including, but not limited to.

It will be appreciated that various of the above-disclosed and other features and functions, or alternatives or varieties thereof, may be desirably combined into many other different systems or applications. Also that various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
